    摘要： The present invention is directed at a system and method for managing and evicting objects stored in a cache. The invention provides a mechanism for determining which objects to evict based on a weight that is calculated for each object stored in the cache. The weight is determined by at least two factors, including file size, file type, primary user, last access time, and the like, and by the relative importance of each of the factors. The weight for each object may be determined autonomously and/or may be determined upon a trigger event. The factors and their relative importance may be obtained from a policy applicable to one or several computers.

    摘要： The present invention provides a novel client side caching (CSC) infrastructure that supports transition states at the directory level to facilitate a seamless operation across connectivity states between client and remote server. More specifically, persistent caching is performed to safeguard the user (e.g., client) and/or the client applications across connectivity interruptions and/or bandwidth changes. This is accomplished in part by caching to a client data store the desirable file(s) together with the appropriate file access parameters. Moreover, the client maintains access to cached files during periods of disconnect. Furthermore, portions of a path can be offline while other portions upstream can remain online. CSC operates on the logical path which cooperates with DFS which operates on the physical path to keep track of files cached, accessed and changes in the directories. In addition, truth on the client is facilitated whether or not a conflict of file copies exists.

    摘要： A system and method for implementing a consistent user name-space on networked computing devices is provided. When a network connection between a local or host computing device and one or more remote computing devices is present, remote items are represented using the same methodology as items located on the host computing device. To the user, remote and local items are indistinguishable. When the network connection is lost or items located on a remote computer are otherwise unavailable, the unavailable items remain represented on the host computing device. Unavailable items are represented in a way that informs the user that the items may not be fully accessed.

    摘要： The present invention is directed at a system and method for managing and evicting objects stored in a cache. The invention provides a mechanism for determining which objects to evict based on a weight that is calculated for each object stored in the cache. The weight is determined by at least two factors, including file size, file type, primary user, last access time, and the like, and by the relative importance of each of the factors. The weight for each object may be determined autonomously and/or may be determined upon a trigger event. The factors and their relative importance may be obtained from a policy applicable to one or several computers.
